Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-75S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X175-75S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 175mm stroke, G3/8 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-75S
A built-in piston magnet supports CMSE/DMSE sensors, and the hard-anodized aluminum barrel is noticeably shorter than a same-bore ISO 15552 unit.
The -75 code means the extend stroke can be shortened by up to 75 mm on-site, giving a usable range of 100-175 mm while the retract end stays fixed. This external stop screw lets you fine-tune the end position without swapping the cylinder. Air connects via a G3/8 port, and adjustable cushions decelerate the load at both ends.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|

| Max (@1.0 MPa) | 286 kgf | |
JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-75S Is Used
Press Fit Tuning
Dial in the exact insertion depth of bearings on-site using the 75 mm extend adjuster, avoiding costly cylinder changes when prototype tolerances shift.
Variable Transfer Stops
Act as an adjustable flight stop on a packaging line, shortening the extend stroke by up to 75 mm to handle different carton sizes without repositioning the mount.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-75S the Right Cylinder?
The -75 mm adjustable window is ideal for sharing a spare across stroke variants or finalizing end positions during machine commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S suffix means a magnet is fitted for CMSE/DMSE switches. For any stroke over 300 mm, guide the load externally to prevent side-load wear on the rod seals.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-75S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. The air port size is G3/8.
The nominal 175 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 75 mm, yielding a usable extend range of 100-175 mm. The retract end remains fixed. This stop sets the end position but does not lock the load; use an external rod lock or pilot-operated check valve to hold a load on air loss.
